HARNESS FRAME FOR LOOMS Filed Nov. 15, 1962 INVENTORS Mia-ER J: K0 YDER United States Patent 3,169,555 HARNESS'FRAME FOR LOOMS Walter J. Koyder and Gerald E. Manross, Meadvilie, Pa., assignors to Talon, Inc., a corporation of Pennsylvania Filed Nov. 15, 1962, Ser. No. 237,846 8 Claims. (Cl. 139-91) and quickly connected to or removed from a jack of a loom with the least amount of effort.

It is another object of this invention to provide a new and novel harness frame which is light in weight and consists of a minimum number of parts which may be easily and conveniently assembled.

It is a further object of the invention to provide a harness frame having an improved detachable connecting means arranged therewith whereby the harness frame may be automatically connected to means carried by a jack of a loom for holding the harness frame securely and firmly in position thereon.

Various other objects and advantages of this invention will be more apparent in the course of the following specifications, and will be particularly pointed out in the appended claims.

In the accompanying drawings, there is shown for the purpose of illustration, an embodiment which our invention may assume in practice.

In these drawings:

FIG. 1 is a front elevational view, partly in section, of the improved harness or heddle frame in accordance with the present invention, showing it attached to a jack of a loom,

FIG. 2 is a side elevational view thereof,

FIG. 3 is a fragmentary view of the bottom portion of the harness frame, partly in section, showing it detached from the jack of the loom.'

Referring more particularly to the drawings, the improved harness or heddle frame of the present invention consists preferably of a pair of identical rectangularshapecl frame or members 2 which are made preferably of flat metallic stock but may be made from any other suitable material. These members are positioned in superimposed relation and are preferably secured together by means of a plurality of rivets 3 so as to provide a space 4 therebetween. Thus, it will be seen that there is provided a rectangular frame having a pair of side portions 5, a top portion 6 and a bottom portion 7.

Centrally of this frame, there is arranged in the space 4 between the members 2, a vertical bar 8 which is movable vertically relative to the frame for a purpose hereinafter to be described. The upper end of this vertical bar 8 extends above the top portion 6 of the frame, as at 9, and has an aperture 10 arranged therein. On the lower end of this vertical bar, there is arranged an extension 12 which extends into the space 4 between the two members 2 at the bottom portion 7 of the frame.

There is arranged in the space 4 between the members 2 at the bottom portion 7 of the frame, a pair of spaced-apart opposed dog members 13 which are pivotally attached to this bottom portion by means of pins 14. On the lower end of each of these dog members 13, there, is arranged a hook-shaped portion 15 which ex- 3,169,555 Patented Feb, 16, 1965 tends below the bottom portion 7 of the frame. The lower extension 12' of the vertical bar 8'is disposed between these' pair of dog members 13 and cooperates with the opposed inner side walls 16 thereof to force these dog'members 13 outwardly away from one another about their respective pivotal connections 14 against the action of the respective leaf springs 17 arranged therewith.

In the space 4 between the frame members 2 at the top portion 6 of the frame, there is arranged preferably a downwardly extending pin-like portion 18 around which there is arranged a coil spring 19 which is disposed in a slotted opening 20 in the vertical bar 8 and which cooperates therewith to urge this vertical bar downwardly at all times.

There is arranged in the space 4 between the members 2 at each side thereof four inwardly extending parallel horizontal cross-bars 21 which are secured to the side portions of the frame by the rivets 3. The inner ends of each of these cross-bars terminate adjacent the sides of the vertical bar 8 centrally of the frame members 2. There is arranged on these cross-bars 21, a plurality of heddles 22 for guiding the warp threads into the loom in a manner well known to those skilled in the art.

On the outer side of each of the hook-shaped portions 15 of the dog members 13, there is provided a notch 23 which cooperate with a pair of pins P carried by jacks J of the loom in a manner to be presently described.

Having described the construction of the improved harness or heddle frame of the present invention, it is assembled on a jack of the loom in the following manner. The extension 9 of the vertical bar .8 is grasped and moved upwardly against the action of the coil spring 19. In such movement, it will be seen that the lower extension 12 of this vertical bar will be moved out of engagement with the inner sides of the dog members 13 thereby permitting these dog members to move toward one another about their respective pivotal connections at 14 until the inner sides abut one another clue to the action of the leaf springs 17 as clearly shown in FIG. 3 of the drawings. V

The harness frame is then positioned on top of the jack so that the lower ends 15 of the dog members 13 are positioned in the space between the pair of opposed pins P carried by a jack J. The vertical bar 8 'is then released and the lower extension 12 carried thereby moves the dog members 13 about their respective pivotal connections 14 so as to position the notches '23 in the outer sides of the portions 15 in engagement with the respective pins P so as to lock securely the harness frame in position on the jack in readiness foroperation. The reverse procedure is followed for removing and detaching the harness frame from the jack. 7

As a result of our invention, it will be seen that there is provided an improved harness or heddle frame which can be easily and quickly assembled on or removed from the jacks of the loom. It will also be seen that the harness frame of the present invention is provided with improved detachable connecting means whereby the harness frame is held rigidly and securely in engagement with the jack of the loom and, at the same time, may be conveniently manipulated to attach or remove the harness frame from its position on the jack.

While we have shown and described an embodiment which our invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustration and description, and that other forms may be devised within the scopeof our invention as'designed in the appended claims.
